ABSTRACT

OBJECTIVE: Kawasaki disease (KD) is the most common cause of coronary artery aneurysm (CAA) in children. The available risk scores to predict intravenous immunoglobulin (IVIG) resistance and CAA were developed in Asian populations in whom their effectiveness has been proven, but data on non-Asian children are limited. This study aimed to evaluate the ability of 5 risk scoring systems to predict IVIG resistance and CAA in Turkey patients with KD. METHODS: Patients with KD were retrospectively evaluated with clinical, laboratory, and echocardiographic findings. Data analyses were performed in 5 scoring systems (Harada, Kobayashi, Egami, Formosa, and Sano). RESULTS: A total of 259 patients (Male: Female, 1.7) were treated for KD in our hospital. The mean age of diagnosis in patients with KD, CAA, and IVIG resistance were 3.31, 2.19, and 2.06, respectively. CAA development and IVIG resistance were seen in 11.6% and 12.3% of cases, respectively. IVIG resistance was detected in 35.6% of patients with CAA. In our study, 5 risk scoring systems were applied to our patients. ROC analysis results were found highest in Kobayashi scoring system for IVIG resistance (AUC, 0.864) and in Harada scoring system for CAA development (AUC, 0.727). CONCLUSION: Harada score was significant in predicting CAA risk, and Kobayashi score was significant in predicting the risk of developing IVIG resistance. It is necessary to determine more specific and sensitive risk scores that increase the risk of IVIG resistance and the development of CAA in Turkey.

ABSTRACT

Background Accurate prediction of coronary artery aneurysms ( CAAs ) in patients with Kawasaki disease remains challenging in North American cohorts. We sought to develop and validate a risk model for CAA prediction. Methods and Results A binary outcome of CAA was defined as left anterior descending or right coronary artery Z score ≥2.5 at 2 to 8 weeks after fever onset in a development cohort (n=903) and a validation cohort (n=185) of patients with Kawasaki disease. Associations of baseline clinical, laboratory, and echocardiographic variables with later CAA were assessed in the development cohort using logistic regression. Discrimination (c statistic) and calibration (Hosmer-Lemeshow) of the final model were evaluated. A practical risk score assigning points to each variable in the final model was created based on model coefficients from the development cohort. Predictors of CAAs at 2 to 8 weeks were baseline Z score of left anterior descending or right coronary artery ≥2.0, age <6 months, Asian race, and C-reactive protein ≥13 mg/ dL (c=0.82 in the development cohort, c=0.93 in the validation cohort). The CAA risk score assigned 2 points for baseline Z score of left anterior descending or right coronary artery ≥2.0 and 1 point for each of the other variables, with creation of low- (0-1), moderate- (2), and high- (3-5) risk groups. The odds of CAA s were 16-fold greater in the high- versus the low-risk groups in the development cohort (odds ratio, 16.4; 95% CI , 9.71-27.7 [ P<0.001]), and >40-fold greater in the validation cohort (odds ratio, 44.0; 95% CI, 10.8-180 [ P<0.001]). Conclusions Our risk model for CAA in Kawasaki disease consisting of baseline demographic, laboratory, and echocardiographic variables had excellent predictive utility and should undergo prospective testing.

ABSTRACT

AIMS: To delineate the risk factors for rupture of congenital aneurysmal fistulas in adult patients. METHODS: We conducted a literature search of the Medline database using Pubmed search interface to identify reports dealing with rupture of congenital aneurysmal fistulas in an adult population. The search included the English and non-English languages between 1963 and 2005. RESULTS: Fourteen adult patients (12 females) with serious and life-threatening complications secondary to aneurysmal fistulas were reported. Mean age was 62.9 years. The ethnic origins of these 14 patients were 9 Asian and 5 Caucasian. Most patients have had no other cardiac malformations. Five patients had a history of hypertension. One patient was asymptomatic. In 13 symptomatic patients, the clinical presentation was cardiac tamponade, pericardial effusion, syncope, heart failure, chest pain, dyspnea, fatigue, distal thromboembolic events with infarction, shock, and/or sudden death. Aneurysmal fistulas were identified in 10 patients; of these 6 were of the saccular type. Rupture occurred in 9 patients (8 females and 1 male). Eleven patients were treated surgically with 1 late death. Two male subjects experienced sudden unexpected cardiac death. CONCLUSION: Rupture of congenital aneurysmal fistulas occurred more often in females. Identified risk factors for rupture, hemopericardium, tamponade, and death were among others saccular aneurysm, Asian ethnic race, origin of the aneurysmal fistulas from the left coronary artery and a history of hypertension may play a role. In this article, we present a literature review of congenital aneurysmal fistulas associated with or without rupture and a case report of a woman with unruptured aneurysmal fistula.

ABSTRACT

Detailed DNA sequencing of the triple-helical domain of type III procollagen was carried out on cDNA prepared from 54 patients with aortic aneurysms. The 43 male and 11 female patients originated from 50 different families and five different nationalities. 43 patients had at least one additional blood relative who had aneurysms. Five overlapping asymmetric PCR products, covering all the coding sequences of the triple-helical domain of type III procollagen, were sequenced with 28 specific sequencing primers. Analysis of the sequencing gels revealed only two nucleotide changes that altered the structure of the protein. One was a substitution of threonine for proline at amino acid position 501 and its functional importance was not clearly established. The other was a substitution of arginine for an obligatory glycine at amino acid position 136. In 40 of the 54 patients, detection of a polymorphism in the mRNA established that both alleles were expressed. The results indicate that mutations in type III procollagen are the cause of only about 2% of aortic aneurysms.
